This collage refers to the artist's interest in sources of energy and power. A battery can be either a portable source of energy, or an instrument that converts chemical to electrical energy. Used as a motif, the battery would have appealed to the artist for its capacity to store or transform energy and in its ability to convert one type of energy to another. Beuys later used the concept of the battery in his series of sculptural works called 'Fonds'.
